Problems solved by technology

However, the rubber is easy to age. After using the sealing surface for a long time, the rubber is easy to stick to the sealing surface, so that the sealing surface must be cleaned when replacing the sealing gasket, which is easy to cause damage to the machine. The installation and use of this gasket are inconvenient. And the mechanical and physical performance analysis of this kind of sealing gasket has no obvious characteristics, and the performance is not good.

Abstract

The invention provides a sealing gasket for refrigeration equipment. The sealing gasket is a multi-layer composite structure, and the multi-layer composite structure includes a natural rubber layer. The front and back of the natural rubber layer are sequentially arranged from inside to outside. An expansion buffer layer, a flame-retardant layer, an anti-corrosion layer and a cold-resistant layer are arranged respectively, and a polytetrafluoroethylene layer is arranged outside the cold-resistant layer. The sealing gasket of the present invention has a multi-layer composite structure, which fully increases the properties of the product such as expansion, flame retardancy, oil resistance, corrosion resistance, cold resistance and frost resistance, and mechanical strength, making the product have excellent overall performance , suitable for refrigeration equipment in the biochemical field.

Description

technical field [0001] The invention relates to a sealing gasket of a refrigeration device. Background technique [0002] Gasket is a kind of material used for sealing inside machinery, equipment, pipelines, etc. [0003] Gaskets are very important in biochemical equipment. In the production process of biochemical equipment, there are often accidents such as equipment failure, production interruption, and material scrapping. The reason is that there are many factors that cause the failure of sealing technology due to damage to sealing components (including sealing gaskets). In addition to ensuring the accurate execution of process parameters in a set of biochemical equipment, sealing components (including sealing gaskets) have another function to avoid three leakages (water, gas, oil, etc.) of electromechanical equipment, which is important to ensure the safety and efficiency of equipment Running, saving energy, protecting the environment, and ensuring the quality of produ...
